Welcome to my Tuesday morning PSA about plastics!

So--I was walking along the Bolstadt beach approach sidewalk here in Long Beach, WA yesterday afternoon, and I started seeing these little orange pellets on the ground that looked a little bit like salmon roe (but probably weren't). So I picked one up, and it was most definitely rubber. I went around picking up every one I could find, and while I didn't keep exact count I probably amassed 50-60 of them. I took this picture before depositing them in the nearest trash can.

These are airsoft gun pellets, and you can buy them in big jars containing thousands of them. That means that someone who decided that the beach was a great place to shoot their airsoft guns could easily litter the place with countless little bits of plastic rubber in less than an hour. We already have a huge problem here with people leaving trash, including tiny bits of plastic, all over the beach (you should see the gigantic mess after 4th of July fireworks when thousands of people come in from out of town, blow things up, and then leave again without picking up after themselves.)

But these airsoft pellets have a particularly nasty side effect. You know how my first thought was "wow, those look kind of like salmon roe?" Well, we have a number of opportunistic omnivore birds like crows, ravens, and several species of gull that commonly scavenge on the beach, especially along the approaches because people often feed them there. If I can catch the resemblance of an orange airsoft pellet to a fish egg, then chances are there are wildlife that will assume they're edible.

Since birds don't chew their food, they probably won't notice that the taste or texture is wrong--it'll just go down the hatch. And since they can't digest the pellets, there's a good chance they might just build up in the bird's digestive system, especially if the bird eats a large number of them--say, fifty or sixty of them dropped on the ground along the same fifty foot stretch of sidewalk. The bird might die of starvation if there's not enough capacity for food in their stomach--or they might just die painfully of an impacted gut, and no way to get help for it. If the pellets end up washed into the ocean, you get the same issue with fish and other marine wildlife eating them, and then of course the pellets eventually breaking up into microplastic particles.

You can get biodegradable airsoft pellets; they appear to mainly be gray or white in color rather than bright screaming orange and green. But "biodegradable" doesn't mean "instantly dissolves the next time it rains." An Amazon listing for Aim Green biodegradable airsoft pellets advertise them as "Our biodegradable BBs are engineered to degrade only with long-term exposure to water and sun and will degrade 180 days after being used." That's half a year for them to be eaten by wildlife.

I don't know, y'all. That handful of carelessly dropped rubber pellets just encapsulates how much people don't factor in the rest of nature when making decisions, even on something that is purely for entertainment like an airsoft gun. We could have had a lot of the same technological advances we have today, but with much less environmental impact, if we had considered the long-term effects on both other people and other living beings, as well as our habitats. We could have found ways from the beginning to make these things in ways that benefited us but also mitigated any harm as much as possible. Instead we're now having to reverse-engineer things we've been using for decades, and sometimes--like the "biodegradable" airsoft pellets--they still have a significant negative impact.

But--at least there are people trying to do things better, thinking ahead instead of just on immediate profit. We're stuck in a heck of a mess here, figuratively and literally, and changing an entire system can't be done in a day. Maybe we can at least keep pushing for a cultural shift that emphasizes planning far into the future--if not the often-cited "seven generations ahead", then at least throughout the potential lifespan of a given product.

Environmental Cleanup: Bioremediation as an Eco-Friendly Solution

Bioremediation is an eco-friendly approach that uses microorganisms or their enzymes to clean up environmental pollutants. It is a sustainable and cost-effective method to treat contaminated soil, water, and air. Bioremediation can be applied to a variety of pollutants, including petroleum, pesticides, and solvents. The process involves various biochemical reactions, microbial interactions, and environmental factors.

The principles of bioremediation are based on the natural processes of microbial degradation and plant uptake. Microorganisms have evolved to use various organic compounds as sources of energy and nutrients. They have a diverse range of enzymes that can break down complex molecules into simpler forms that can be utilized by the cell. In bioremediation, microbial degradation is enhanced by adding nutrients, oxygen, and other growth-promoting factors to the contaminated site. This can be achieved by various techniques, such as bioaugmentation, biostimulation, and phytoremediation.

There are several types of bioremediation techniques that can be applied to different types of pollutants and environments. The most common ones are in situ bioremediation, ex situ bioremediation, bioventing, biosparging, and bioreactors.

Bioremediation has been applied to a wide range of environmental pollutants and industries. Petroleum, heavy metal, pesticide, industrial waste, and landfill leachate contamination are some of the common applications of bioremediation.

Compared to traditional remediation techniques, such as excavation and incineration, bioremediation offers several benefits. It is sustainable, cost-effective, versatile, and non-invasive. Therefore, bioremediation is a promising eco-friendly solution for environmental cleanup.

It took 90 days for the fungi to degrade 27 per cent of the plastic tested, and about 140 days to completely break it down, after the samples were exposed to ultraviolet rays or heat.

Chemical engineering professor Ali Abbas, who supervised the research team, said the findings were significant.

"It's the highest degradation rate reported in the literature that we know in the world," the professor said.

Millions of Birds Now Migrating Safely Through Darkened Texas Cities After Successful Lights Out Campaign https://www.goodnewsnetwork.org/millions-of-birds-now-migrating-safely-through-darkened-texas-cities-after-successful-lights-out-campaign/

"Despite a huge amount of political opposition from the chemical industry, the US Environmental Protection Agency (EPA) announced its first regulations aimed at limiting quantities of PFAs, or ‘forever chemicals,’ in American drinking water.

For decades, Polyfluoroalkyl substances or PFAs have been used for coatings that resist fire, oil, stains, and water and are now found in a wide variety of products like waterproof clothing, stain-resistant furniture, food packaging, adhesives, firefighting spray foams, and non-stick cooking surfaces.

There are thousands of PFAS compounds with varying effects and toxicity levels, and the new EPA regulations will require water utilities to test for 6 different classes of them.

The new standards will reduce PFAS exposure—and thereby decrease the health risk—for 100 million people in the U.S.

A fund worth $1 billion for treatment and testing will be made available to water utilities nationwide—part of a $9 billion investment made possible by the 2021 Bipartisan Infrastructure Law to assist communities impacted by PFAS contamination.

“Drinking water contaminated with PFAS has plagued communities across this country for too long,” said EPA Administrator Michael S. Regan in a statement Wednesday.

Under Regan’s leadership, the EPA began in 2021 to establish a roadmap for dealing with widespread PFAS contamination, and so far they’ve gathered much data, including monitoring drinking water, and begun requiring more reports from businesses about use of the unregulated substances.

The agency reported that current peer-reviewed scientific studies have shown that exposure to certain levels of PFAS may lead to a myriad of health issues that are difficult to specify because of the variety of compounds coming from different places.

Regardless, the 66,000 water utility operators will have five years to test for the PFAS pollution and install necessary technology to treat the contamination, which the EPA estimates that 6%–10% of facilities will need. [Note: Deeply curious where they got a number that low, but anyway.]

Records show that some of the manufacturers knew these chemicals posed health hazards. A few major lawsuits in recent years have been settled that sought to hold chemical companies, like 3M, accountable for the environment damage.""

I know I shouldn't really be surprised that plastic recycling is a scam by the petrochemical industry to hobble momentum toward legislation limiting the production of plastics, but it's still really depressing.

of fucking course.....they fucking coated paper straws with pfas......its a fucking nightmare

--

Long-lasting 'forever chemicals', which can cause damaging health issues, found in 18/20 brands of paper straws

In the first analysis of its kind in Europe, and only the second in the world, Belgian researchers tested 39 brands of straws for the group of synthetic chemicals known as poly- and perfluoroalkyl substances (PFAS).

PFAS were found in the majority of the straws tested and were most common in those made from paper and bamboo, the study, published in the peer-reviewed journal Food Additives and Contaminants, found.

PFAS are used to make everyday products, from outdoor clothing to non-stick pans, resistant to water, heat and stains. They are, however, potentially harmful to people, wildlife and the environment.

They break down very slowly over time and can persist over thousands of years in the environment, a property that has led to them being known as "forever chemicals."

They have been associated with a number of health problems, including lower response to vaccines, lower birth weight, thyroid disease, increased cholesterol levels, liver damage, kidney cancer and testicular cancer.

"Straws made from plant-based materials, such as paper and bamboo, are often advertised as being more sustainable and eco-friendly than those made from plastic," says researcher Dr Thimo Groffen, an environmental scientist at the University of Antwerp, who is involved in this study.

"However, the presence of PFAS in these straws means that's not necessarily true."

A growing number of countries, including the UK and Belgium, have banned sale of single-use plastic products, including drinking straws, and plant-based versions have become popular alternatives.

A recent study found PFAS in plant-based drinking straws in the US. Dr Groffen and colleagues wanted to find out if the same was true of those on sale in Belgium.

To explore this further, the research team purchased 39 different brands of drinking straw made from five materials -- paper, bamboo, glass, stainless steel and plastic.

The straws, which were mainly obtained from shops, supermarkets and fast-food restaurants, then underwent two rounds of testing for PFAS.

The majority of the brands (27/39, 69%) contained PFAS, with 18 different PFAS detected in total.

The paper straws were most likely to contain PFAS, with the chemicals detected in 18/20 (90%) of the brands tested. PFAS were also detected in 4/5 (80%) brands of bamboo straw, 3/4 (75%) of the plastic straw brands and 2/5 (40%) brands of glass straw. They were not detected in any of the five types of steel straw tested.

The most commonly found PFAS, perfluorooctanoic acid (PFOA), has been banned globally since 2020.

Also detected were trifluoroacetic acid (TFA) and trifluoromethanesulfonic acid (TFMS), "ultra-short chain" PFAS which are highly water soluble and so might leach out of straws into drinks.

The PFAS concentrations were low and, bearing in mind that most people tend to only use straws occasionally, pose a limited risk to human health. However, PFAS can remain in the body for many years and concentrations can build up over time.

"Small amounts of PFAS, while not harmful in themselves, can add to the chemical load already present in the body," says Dr Groffen.

It isn't known whether the PFAS were added to the straws by the manufacturers for waterproofing or whether were the result of contamination. Potential sources of contamination include the soil the plant-based materials were grown in and the water used in the manufacturing process.

However, the presence of the chemicals in almost every brand of paper straw means it is likely that it was, in some cases, being used as a water-repellent coating, say the researchers.

The study's other limitations include not looking at whether the PFAS would leach out of the straws into liquids.

Dr Groffen concludes: "The presence of PFAS in paper and bamboo straws shows they are not necessarily biodegradable.

"We did not detect any PFAS in stainless steel straws, so I would advise consumers to use this type of straw -- or just avoid using straws at all."

Do people know most paper receipts are harmful to their health?

I'm going to get up on my soapbox for a minute, but do people realize how pretty much everyone is being overloaded with endocrine disruptors like BPA/BPS on a near-daily basis??

I don't think many people understand that ever since most of the world transitioned to thermal paper receipts (cheaper than ink), almost every receipt you handle from the gas station to the grocery store to the Square terminal printer at the local co-op is coated with Bisphenol-A (BPA) or its chemical cousin Bisphenol-S (BPS).

These chemicals have not only been proven to cause reproductive harm to human and animals, they've also been linked to obesity and attention disorders.

Not sure if your receipt is a thermal receipt? If you scratch it with a coin and it turns dark, it's thermal.

BPA/BPS can enter the skin to a depth such that it is no longer removable by washing hands. When taking hold of a receipt consisting of thermal printing paper for five seconds, roughly 1 μg BPA is transferred to the forefinger and the middle finger. If the skin is dry or greasy, it is about ten times more. 

Think of how many receipts you handle every day. It's even worse for cashiers and tellers, who may handle hundreds in a single shift. It is also a class issue, since many people who work retail and food service are lower-income and will suffer worse health consequences over time from the near-constant exposure.

Not only that, receipts printed with thermal ink are NOT recyclable, as they pollute the rest of the paper products with the chemicals.

People don't know this and recycle them anyway, so when you buy that "green" toilet paper that says "100% recycled"? Yup, you are probably wiping your most sensitive areas with those same chemicals (for this reason, I buy bamboo or sugarcane toilet paper as a sustainable alternative to recycled paper).

This page from the Minnesota Pollution Control Agency has some good links if you want to learn more.

As consumers, we need to demand better from our businesses and from our governments. We need regulation of these chemicals yesterday.

If you are a buyer or decision-maker for a business, the link above also contains a shortlist of receipt paper manufacturers that are phenol-free.

If you work at a register, ask customers if they want a receipt. If they don't and you can end the transaction without printing one, don't print one!

As a consumer, fold receipts with the ink on the inside, since that's where the coating is. Some more good tips here.

And whatever you do, DO NOT RECYCLE THERMAL RECEIPTS

"Our filter, unlike plastic filters, does not contribute to further pollution as it uses renewable and biodegradable materials: tannic acids from plants, bark, wood and leaves, and wood sawdust—a forestry byproduct that is both widely available and renewable."

"In their research, the team analyzed microparticles shed from widely-used tea bags made of polypropylene. They observed that their technique, termed “bioCap,” captured between 95.2 percent and a staggering 99.9 percent of plastic particles in water, depending on the plastic type. When tested in mouse models, the process was proven to prevent the accumulation of microplastics in the organs"

They said this solution can be scaled up in places like water treatment plants and scaled down for use in the home as well. This is amazing news considering microplastics are one of the biggest problems impacting health these days.

Researchers in the United States and China have discovered a curious link between air pollution and suicide rates that prompts us to reconsider how to approach this issue. China's efforts to reduce air pollution have prevented 46,000 suicide deaths in the country over just five years, the researchers estimate. The team used weather conditions to tease apart confounding factors affecting pollution and suicide rates, arriving at what they consider to be a truly causal connection. The results, published in Nature Sustainability, unearth air quality as a key factor influencing mental health.
